Microchip Technology, Inc. DC DC Switching Controllers MCP1631VT-E/ST

The MCP1631VT-E/ST is a high-speed analog pulse width modulator (PWM) designed for intelligent power system applications. It operates at a frequency of 2 MHz and supports programmable switching battery charger designs. This device features peak current mode control and voltage mode control options, with high voltage variants capable of operating from +3.5V to +16V input. The MCP1631VT-E/ST provides regulated output voltage options of +5.0V or +3.3V, delivering a maximum current of 250 mA. Integrated features include an error amplifier, battery current and voltage sensing amplifiers, an overvoltage comparator, and a high current low side MOSFET driver with a peak current of 1A. The device also includes a shutdown mode that reduces quiescent current to 2.4 µA and has built-in overtemperature protection and undervoltage lockout (UVLO). It is available in multiple package types, including 20-lead TSSOP and SSOP, making it suitable for various applications such as high input voltage programmable battery chargers and LED lighting systems.
